My invention relates to washing machines l of the type wherein the tub is stationary, and is commonly designated as a momentum washer. j

The object of my invention, is to provide an easy running machine, and one which will be simple in construction and not likely to get out of order.

A further object, is to provide a machine in which there will be no dead centers to interfere with the starting of the machine.

ln the accompanying drawings forming part of this specication, Figure 1, is a side elevation of a Washing machine embodying my invention, Fig. 2, is a vertical sectional view of the same, Fig. 3, is a bottom view, the fly wheel being partially broken away to illustrate the driving mechanism, Fig. 4, is a detailed view of a modified construction of the o erating lever, Fig. 5, is a detailed se`ctionallview showing a portion of the driving mechanism. l

ln the drawing, 2 represents a tub of ordinary type supported on legs 3 which fit Within sockets 4 provided in castings 5 secured to the bottom of the tub.

6 is a hollow standard centrally mounted in the tub and 7 is a shaft within said standard and projecting above and below the same. rlhe upper end of said shaft is secu red to a sleeve S which has a ball-bearing on the upper end of said standard and iii-closes said standard and supports a rubber head i() a suitable distance above thc bottom of 'the tub. A pinion 11 is secured on the shaft 7 below the tub and meshes with a rack bar l2 that is connected to a crank pin 13%, eceenl,trically mounted on a beveled gear 14, that is carried by a plate 5. A shaft lhas bearings at one end in a block 16 on the shaft 7 and at its other end in a bracket 17 depend- A gear 18 is mounted on said shaft, and meshes with the gear 14 and a pinion 19 is also mount-ed on said shaft and engaffes a gear 20 carried by a fly-wheel 21 loosely mounted on the shaft 7 and resting on a ball-bearing 22 thereon. A drive wheel 23 is secured on the outer end of the shaft 15 and has a series of teeth 24. A lever 25 is pivoted at 26 on the upper portion. of the tub, and bars 27 and 27@L are pivoted at their upper ends on said lever, and are provided with a series of pins 28 to engage the teeth 24 being-yieldingly held in contact with said `teeth by a spring 29. One of the bars depends on one side of the wheel, `and the other on the other side, and consequently, as the lever 25 is oscillated, the bars will be reciprocated vertically and a revolving movement will be im )arted to the 'wheel 23 and its shaft.

n F ig. 4, l have shown a slight modifica-v tion which consists in providing a curved lever 30 centrally ivoted and having handles 31 at each end). the lever, stands in front of it with a hand on each end thereof, and upon` rocking the lever, the bars connected therewith, will be reciprocated and the toothed wheel revolved. Sufficient momentum will be obtained through the use of the fly-wheel to insure a uniform continuous movement of the rubber head. An anti-friction roller 32 is provided on one side of the rack bar l2 to form a guide therefor, and hold it in engagement with the teeth of the inion. operation of the machine, t e pins 28 will engage the square faces of the teeth 24, and as one bar is transmitting power from the operating lever to the shaft, the other bar will be sliding over the teeth of the wheel preparatory to engaging the teeth on the return stroke of the lever. One bar is therefore operative while the other is idle, and a continuous motion results from their engagement with the toothed wheel.'

l claim as my invention:

1. In a machine of the class described, a shaft, a pinion secured thereon, a rack bar engaging said pinion, a )ivoted gear having a crank pin whereon sai rack bar is mounted, a horizontal shaft, a gear thereon meshe ing with said pivoted gear, a pinion secured on said horizontal shaft, a fly wheel loosely mounted on said first named shaft and geared to said pinion, and means for drivingr saidhorizontal shaft.

2. In a machine of the class described, a vertical shaft, a horizontal shaft having a driving connection with said vertical shaft, a wheel secured on said horizontal shaft and having a series of teeth, a pivoted lever, bars pivoted at their upper ends on said lever and depending one on each side of said wheel and having a series of pins to engage the teeth of said wheel, one of said bars sllpping 'lhe person operating In the over the teeth of said Wheel while the pins of said other bar are in working engagement therewith, substantially as described.

3. In a machinevof the class described, the

combination with a shaft and a pinion secured thereon, of a rack bar engaging said plnlo'n, a p1voted gear having a crank pm whereon said rack bar 1s mounted, a horizontal shaft, a gear thereon meshing with said pivoted gear, a pinion secured on said horizontal shaft, a ly wheel loosely mounted on said irst. named shaft and geared to said pinion, a wheel secured on said horizontal shaft and having a series of teeth, a pivoted y lever, bars pivoted at their upper ends on said lever and depending one on each side of said wheel and having a series of pins to engage the teeth ofV said wheel, one of said bars slipping over the teeth of said wheel while the pins of the other bar are in working enp gagement therewith.

4 In a machine of the class described, a

vertical shaft, a pinion secured thereon, a

horizontal shaft having a driving connection a crank pin whereon said rack bar is mount? ed, a horizontal shaft, a gear secured thereon and meshing with said pivoted gear, and a ily wheel having a driving connection with said horizontal shaft.

In witness whereof, I have hereunto set my hand this 10th day of August 1908.
